JONAS NORTHROP, or HOPEDALE, MASSACHUSETTS, ASSIGNOB To HornnALE MAun- FACTURING COMPANY, or HOPEDALE, MASSACHUSETTS,

' sAcHUsn'TTa T 0 all whom it may concern:

Be it known that I, JONAS Noer inor, a citizen of the United States, residing at Hopedale, in the count-y of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Loom- Temples; and -I do hereby declare the following to be a full, clear, and exact descrip--- tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an provement in loom-temples. Y

The objectoi? the invention is toreorganize and improve the construction of.

loom-temples in order to secure greater durability of parts, particularly to stand the wear incident to the reciprocation of the temple rod, and in which the wear may be taken up by adjustment of the parts and then adequately secured in the readjusted position.

A further object. of the invention is to produce an efiicient and durable contrivance for holding the temple in inoperative position.

Other features of the invention will bepointed out in the specification.

To the above ends the present invention consists in the loom-temple hereinafter described and particularly defined in the claims. p

In the accompanying drawings illustrating-the preferred form of the invention, Figure 1 is a side elevation of the temple; Fig. 2 is a front'elevation of the loom pod and cap; Fig. 3 is a-plan of the temple; Fig.

4 is a longitudinal, vertical section of the temple rod and guide; and Figs. 5, 6 and 7 are cross-sections taken on the lines 5 66 and 77 respectively of Fig. 4. The temple rod. 1 havinga goose-neck 2 supports at its end the temple pod 3 covered with the temple cap t. The temple heel 5 is secured to the temple pod in the usualmanner by the screws shown in Fig, 3. The temple rod 1 is supported in a rod guide 6, in turn secured'tothe temple support 7 by means of bolts 8, the bolts passingthrough the slot 9 in the flange 10 of the rod guide 6. Referring to Figs. 5, 6 and 7, wherein the temple rod 1 is shown in cross-section, it will be seen that it is substantially semi-cylindrical in form, being grooved lQIlgltlldlIltlllY upon its lower side atll, and provided with oom-TEMPLE.

lateral bearings 12 and 13. These bearings 12 and 13 rest upon the bearings 14: and 15 ot' the rod guide 6 which is also of substantially semi-cylindrical form, being correspondingly and oppositely grooved at 16. These two grooves 11 and 16 together form a substantially cylindrical spring cavity for receiving the temple-rod spring 17, which is a helical compression spring having one end engaging the-spring lug 18 formed on the 5 end of the rod-guide 6, and its other end engaging the spring lug 19 pro ecting down from the under side of the temple rod into the spring cavity 16 of the rod guide. The spring 17 normally tends to press the temple-rod to the left, as viewed in Figs. 1, 3 aud t, thereby holding the temple in forward position. The templc-rod stop 20 limits the forward movement of the temple rod. It is formed integral with the forward end of the rod guide 6. The spring lugs 18 and 19, together with the lateral bearings of the rod. form a part of the guiding devices for controlling the movements of the temple rod. i The bearings described form the principal hearings between the rod and rodguide. A further bearing isprovided by grooving the upper Side of the temple rod from end to end to receive a supplemental templc'rod guide 21 which is secured to the rod guide proper 6 by means of the screw bolts 22 and r 23 which pass through holes in the supplemental guide 21, andare screwed into the spring lug l8 and temple rod stop 20 respectively, and secured in adjusted position by means of lock nuts 24 and The heads of the screw bolts 22 and 23 are received in recesses'in the supplemental guide 21, and hold such guide in adjusted position in the groove in the top of the temple rod 1. As the bottom of the supplemental guide 21 wears into the groove in the top of the temple rod, and as the lateral bearings bet-ween the rod guide G and the rod 1 wear away, the screw bolts 22 and 23 will be screwed in to take up such wear, and to maintain the parts in proper bearing relation, and when so taken up they will be set in fixed position by the set nuts 24 and 25. The temple rod 1 is slotted at 26'and 27 to allow the reciprocation thereof without initrference with the shanks of the screw bolts 22 and 23. It will be observed that the spring lugs 18 and :19, and the temple rod stop 20,- are the cavitiesiwhich they enter, "so that wheiithe parts wear, adjustment may be had with out being prevented by the bottoming of these lugs andstop in the cavitie's'which re-' ceive them.

When it is desired to push the rod back in order to obtain access to the fell, as in picking out a broken weft, the o )erative will push the temple backward until the projection 28 on the under side of the temple rod springs into the recess 29 formed in the upper side of the rod guide (3. It is to be noted that when the rod is thus pushed back, the forward end of the temple rod is only supported from upward movement by the supplemental rod guide 21, and that such forward end of the temple rod slide will pass over the projection 30 by reason of the upward spring of the more or less flexible supplemental rod guide 21, as the pressure is exerted on this member at a distance from the screw bolt 22. The resilience of the supplemental rod guide 21 is sutlicient to llOt the projection 28 in the recess 29 against the pressure of the spring 17 until the operative knocks it loose or withdraws it forcibly therefrom.

The front elevation of the temple pod and'cap, shown in Fig. 2, taken in connection with the end view shown in Fig. 1, show the construction of the cap and pod. The cap has a flat bearing surface 81 which rests u on the bearing surface 32 of the pod. '1 his surface embraces the temple pins and supports them between the pod and cap. The contact surfaces 31 and 32 are indicated in Fig. 2 by the line 83. Inclined contact surfaces 34 and 35, both in the front and in the rear of the surfaces 31 and 32, serve to hold the cap and pod from any relative movement. with relation to each other. The cap screw 36 secures the parts rigidly in correct. relative position. 'lhe inclined contact surfaces 34 and 35 make cooperating projections and recesses on the pod and cap for maintaining the correct relative position retpi 1 red.

t will be observed that the temple rod is )rovided with laterally extended, wider, arge bearings between it and the rod guide which supports the rod so that the wear will be slow, and the parts will long maintain their correct adjusted position. Also that when wear does occur, it can be expeditiously and etliciently taken up bv tightening the screw bolts 22 and 23. No other operation is necessary to take up the wear. lhe locking of the temple in inoperative position by means of the cooperating projection 28 and recess 29 is etlicient-ly secured by reason of the resilient pressure exerted by the supplemental rod guide upon the rod to hold its projection 2 in the recess.
